A historical study of the medieval silk industry of Lucca, Italy, covering its origins in the eleventh century, sources of raw silk, and the putting-out system linking merchants and artisans. It describes throwing, boiling, dyeing, warping and draw-loom weaving, the role of designers, and the fabrics produced, including baldachin, samite, sendal, diasper, ciclatoun, satin and pile-on-pile velvets. It also treats the uses of Lucchese silk by the Church and royal courts, the merchant companies and foreign markets, and the industry's decline from the later fourteenth century on. Six plates show Lucchese textiles and the article ends with a bibliography.
